“…There is a gap in the design approaches to GIS. Few systems offer the user a way of developing macros graphically and little emphasis has been given to the issue of reuseability apart from Egenhofer and Bruns (1995) and the work of Standing and Roy (1995). A visual functional programming design offers a consistent, strongly typed environment where users can develop there own higher order functions.…”

Developing macro queries in software systems is a complex task for many users. Geographical information systems (GIS) are large software systems that require much effort to develop expertise in. A functional programming design approach has a number of distinct strengths that can be represented in a graphical query language interface to aid users in macro query development. A visual functional query language (VFQL) for Geographical InformationSystems is presented and its strengths and weaknesses discussed. The system is based on a visual functional programming design approach. This offers a consistent, nonprocedural, strongly typed environment where users can develop their own higher order functions. The approach integrates functional programming, visual programming and knowledge and rules.VFQL's effectiveness is evaluated compared with a text based command language for GIS macro query development. The results of an experiment indicate that users could develop solutions to simpler tasks more quickly and with fewer errors than a comparative text based command language. On more complex tasks there was no significant difference. From this we deduce that VFQL demonstrates certain design features to help the development of macros or small programs for users but that the complexity of the problem in difficult tasks is likely to be the most important determinant of the error rate and time to complete the task.

“…It has been demonstrated [12] that such an approach benefits from the incorporation of guards which prevent users from stringing inappropriate operations together. This capability involves the specification of the data type requirements and outputs of each operation known to the system.…”

This paper analyses some approaches to enhancing user interaction with high-functionality systems such as geographical information systems. Graphical approaches derived from the direct manipulation tradition are compared and contrasted with intelligent systems approaches. An implementation of one particular approach, based upon AI planning, is presented, and alternative user interfaces to that system are analysed. The benefits of a quite novel form of goal-based or declarative interaction are described.
